I.S. EN 1090-4:2018

This European Standard specifies requirements for the execution, i.e. the manufacture and theinstallation, of cold-formed structural steel members and sheeting and cold-formed structures for roof,ceiling, floor, wall and cladding applications.This European Standard applies to structures designed according to the EN 1993 series.This European Standard applies to structural members and sheeting to be designed according toEN 1993-1-3.This European Standard may be used for structures designed according to other design rules providedthat conditions for execution comply with them and any necessary additional requirements arespecified.This European Standard also specifies requirements for the execution i.e. the manufacture and theinstallation of structures made from cold formed profiled sheeting for roof, ceiling, floor and wallapplications under predominately static loading or seismic loading conditions and their documentation.This European Standard covers sheeting of structural classes I and II according to EN 1993-1-3 used instructures.This European Standard covers structural members of all structural classes according to EN 1993-1-3.Structural sheeting are understood here to be:— profiled sheet, such as trapezoidal, sinusoidal or liner trays (Figure 1), orStructural members are understood here to be:— members (linear profiled cros sections) that are produced by cold forming (Figure 2).This European Standard also covers:— not welded built-up sections (Figure 2b and 2c);— cold-formed hollow sections including the welding of the longitudinal seam, not covered byEN 10219-1;perforated, punctured and micro profiled sheeting and members;This European Standard also covers spacer constructions between the outer and inner or upper andlower skins for roofs, walls and ceilings made from cold-formed profiled sheeting and the connectionsand attachments of the afore mentioned elements as long as all are involved in load transfer.This European Standard covers steel profiled sheeting for composite floors, e.g. during installation andin stage of pouring concrete.Composite structural members where the interaction between dissimilar materials are an integral partof the structural behaviour such as sandwich panels and composite floors are not covered by thisstandard.This European Standard does not cover the necessary analyses and detailing and execution rules forthermal insulation, moisture protection, noise control and fire protection.This European Standard does not cover regulations of roof cladding and wall cladding, produced bytraditional plumber methods or tinsmith methods
